Now there are more and more graphite powders on the market, and the quality of graphite powders is mixed. So, what method can we use to distinguish the advantages and disadvantages of graphite powders? What is the harm of inferior graphite powder? Let’s take a brief look at it by editor Furuite Graphite.
Distinguishing method of graphite powder:
1. Pinch it with your hands to feel smooth, which indicates good quality.
2. Good graphite powder is black and bright
3. The more you sink in the water, the better the quality.
4. Low-temperature calcination method, when graphite powder is calcined at 1200 degrees, the less the current color changes, the better (the current color will turn white after calcination).
Harm of inferior graphite powder:
The inferior graphite powder has low strength, poor thermal shock resistance, poor high temperature resistance and oxidation resistance, no corrosion resistance, and is not easy for precision machining. As graphite powder is widely used, if we choose inferior graphite powder, it will not only affect our use effect, but also affect our product quality. Therefore, we must keep our eyes open when choosing graphite powder.
